    You seem to be attempting to differentiate (\tan x)^3, which is a different thing.

    You can differentiate \tan (x^3) in a similar way to how you would differentiate e.g. \tan (3x). Does this make sense?

    I'm not sure quite what you did. Can you explain your thought process?

    By the chain rule you have \displaystyle \frac{\mathrm d}{\mathrm dx} x^3 \cdot \frac{\mathrm d}{\mathrm d(x^3)} \tan(x^3).

    Ah yes that was what caused the confusion.
